Methods: The association between the blood pressure control and the clinical characteristics was evaluated in 1359 patients with type 2 diabetes mellitus. Results: The number of antihypertensive agents was 1.5 ± 1.4 (2.0 ± 1.2 among the 990 patients with hypertension). The proportion of patients taking no antihypertensive agents was 29%, 22% were taking one, 29% were taking two and 21% of the patients were taking three or more antihypertensive agents. The value of the ankle-brachial pressure index significantly decreased with the increase in the number of antihypertensive agents even if the blood pressure was corrected to the target value. The values of brachial-ankle pulse wave velocity and carotid intima-media thickness were also increased. The prevalence of risk factors for atherosclerosis, such as obesity, hyperlipidemia, chronic kidney disease, hyperuricemia and anemia was significantly elevated with the number of agents. Conclusions: The number of antihypertensive agents simply reflects the grade and risk of atherosclerosis in patients with type 2 diabetes mellitus.展开更多

It was found that (1) EH patients had a pronounced defect of both the active and passive trans-port of sodium ions by the erythrocytes; (2) a higher plasma level of EDLC was detected in EH pa-tients as compared with that of the control, but the changes of EDLC and soudium pump were notparallel; (3) after the administration of nifedipine and prazosin, the function of sodium pump wasmarkedly improved and the plasma level of EDLC decreased. In addition, the relationship betweenthe transport of sodium ions by erythrocytes and the pathogenesis of EH, and the effects of anti-hypertensive agents were discussed.展开更多
